Do the Darton sleeves come in 4.00" bore? I'd like to do a 4.00 x 4.00 motor with an Al block. I'm quite aware that the iron block comes with a 4.00" bore, but I'd like to do FI with this block and would rather not put any additional weight on the front of the car.

And...if I were to do that, would the price be the same as the 4.125" sleeve?

Thanks.

Yes Darton makes a sleeve that can make a 4.000 in bore and will handle the boost.

Thanks everyone for the quick responses. I'm looking to do a TTi setup damn near identical to the Incon set. Normal street driving at 5-6psi with the engine built to handle ~12psi...maybe more <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> for track work. It sounds like the sleeves are available, my only other question would be concerning the thickness. Would a sleeve with an intended finished diameter of 4" be any thicker than the 4.125". For my app, would it even matter?

Nate, how much boost/hp have you tested with?

How thick are the 4.100 sleeves?

The Darton sleeves we order are 4.050" bore when they arrive. I would suggest checking Darton's website, or giving them a call to see if the LS1 sleeve is available in a smaller bore size. Pricing should be close to the same if they offer that size.

How much power are you planning to make? If you plan to stay N/A, and make less than 500hp, the factory sleeve can handle a .010" oversize, but that won't leave you any room for repairs later, or if you plan on running high boost, that would not be the best way to go.
